Version History

Introduced in R2009a

R2025a: Preferences window renamed to Settings window, new location for imshow settings

The Preferences window has been renamed to the Settings window and preferences are now referred to as settings.

Starting in R2025a, access imshow settings under MATLAB > Image Display.

R2023a: Update preferences interactively in MATLAB Online using the MATLAB Preferences window

Before R2023a, in MATLAB Online™, you could only access and update toolbox preferences programmatically using the iptgetpref and iptsetpref functions, respectively. You could not set toolbox preferences interactively.

Starting in R2023a, in MATLAB Online, you can additionally access and set toolbox preferences interactively using the MATLAB Preferences window.

• Access display settings for the imshow function under MATLAB > Image Display.

• Access display settings for the Image Tool, as well as an option for enabling hardware optimizations, under Image Processing Toolbox.

There is no change to the MATLAB Preferences window in MATLAB desktop.
